VENTILATING WINDOW SASH Arm/@MFV Patented Mar. 31, 1931 PATENT QFFECE EDWARD S. KELLY, OF ST. LOUIS,'MISSOURI vENTILATING WINDOW sAsH Application filed August 8, 1929.

This invention relates generally to window sashes, and more particularly to an improved window sash provided with louver boards capable orP pivotal adjustment with respect to the sash to provide Ventilating apertures through the sash, the predominant object ot the invention being to construct an improved window sash oi"- this type which is at once et simple construction and eihcient in operation.

Briefly stated, the invention comprises a window sash, either of the hinged or sliding type, provided with the usual top, bottom, and side members. Arranged within the frame provided by the top, bottom, and side members referred to, in the position ordinarily occupied by the pane of glass of a window sash, is a plurality of louver boards. kEach of the louver boards is pivotally supported at its upper end, and the lower end thereoi is capable of being moved outwardly in an arc of a circle to provide a Ventilating space between the outwardly moved lower end of the louver board and the upper end of the louver board disposed immediately beneath the louver board so adjusted.

An extremely important feature of the invention resides in the tact that each louver board at the opposite sides thereof is provided with shields, which prevent inclement elements, rain, wind, and snow, from being driven under the outwardly adjusted louver boards at the opposite sides thereof. Because of this arrangement the louver boards of my improved sash may be maintained in slightly open positions even during a heavy rain storm, without danger of rain passing into the room with which the sash is associated, as the inclination of the louver boards will shed rainwater and snow away from the 4o Ventilating openings beneath the louver boards, and the shields will prevent rainwater, wind, and snow from passing beneath the louver boards at the sides thereof.

Fig. 4 is a fragmentary cross-section illustrating a window sash ot the'sliding type embodying the principles of my invention.

In the drawings, wherein is shown Jfor the purpose of illustration, merely, one embodiment of the invention, A designates a window frame of ordinary construction, said frame A comprising the usual side members B, top member C, and sill D. Arranged for sliding movement in the window trame A in the usual manner is an upper window sash E, and arrangedl in the lower portion of the window frame A is a pair of my impro-ved louver window sashes F (Fig. l). The window sashes F illustrated in Fig. l are ot the French window type, said sashes being hinged at the points designated by the reference character F to the window frame A. and the inner edges thereof meeting at the approximate center of the window, at which point a suitable fastening device Gr is employed for the purpose of maintaining the sashes F in closed positions. VVhiie I illustrate the sashes F in Fig. l as constituting the lower sash ot the window, it is obvious that said sashes F may be employed as the upper window sash, and also, while l show the hinged sashes F in l, may, of course, employ instead a sliding sash such as that illustrated in Fig. 1i.

Referring now to the sashes illustrated u in Figs. l, 2,v and 3 of the drawings, each thereoic comprises a trame H composed of side nembers l and 2, a top member 3, and a bottom member t. Arranged within the frame H of each sash F is a vertical row of louver g5 boards 5, said louver boards comprising each a strip of glass or other suitable material supported wit-hin a rectangular frame 6 (Fig. 3), the marginal edge of said strip of material 5 being confined in a rectangular recess provided bythe frame 6. Arranged at the upper edge of each louver board 5 is a rod 7 said rod being extended transversely of the frame Hof the sash of which its associated louver by suitable brackets secured to the opposite side members l and 2 ot said frame. Each louver b-oard 5 is pivotally connected to the associated rod 7 by means of a semicircular clip 8 (Fig. 3,), which is secured to the rec- 100 lil tangular frame 6 of the louver board and embraces said rod, said clips being spaced longitudinally of the associated louver board for a purpose to be hereinafter set forth.

lt is obvious, in view of the arrangement of the louver boards as just described, that the lower end portions of said louver boards may be moved outwardly with respect to the upper portion of the louver boards disposed immediately beneath the louver boards so ad j usted to pro ride Ventilating spaces between the adjusted louver boards and the louver boards located beneath the same.Y`

Mounted for pivotal movement on each of the rods 7 is a locking device, which comprises an elongated member 9 extended longitudinally of said rod and provided with an upwardly curved forward end portion 10. Each locking device is formed of a pair of pieces of material which are secured together to provide a unitary structure, and at the transverse center of the locking device the pieces of material referred to are shaped to provide an eye 11 through which the rod 7 extends, whereby the locking device is supported on the rod. t the end of the locking device 9 opposite to the end thereof at which the curved portion is "located, said locking device is provided with an operating portion 12 which is located at the inside of the window,

he curved portion 10 being located at the outer face of said window. Each of the locking devices extends continuously7 longitudinally of the associated rod 7, and said locking` device is provided with recesses 13 spaced longitudinally thereof in which the clips 8 of the louver board located beneath the locking device are disposed. 1n view of this arrangement, it is plain that one of the louver boards and one of the locking devices are supported by each rod 7.

Secured at opposite sides of each of the frames H of the sashes F are elements 14, which provide vertically disposed pockets 15, said elements being extended from the top face of the lower member d of said frame H to the lower face of the top member 3 thereof, and said elements being secured by suitable means to the side members 1V and 2 of said frame H. The elements 14 are each substantially U-shaped in cross-section, as shown in Fig. 2, and secured to each of said el-ements and to the associated members 1 or 2 of the frame H is a channel member 16. Arranged at the opposite sides of each of the louver boards 5 are facing elementsl? which constitute parts of the rectangular frame 6 of said louver board, each of said facing elements being provided with an inwardly turned flange portion 18, the inner end of which' contacts with the outer face of the adjacent side member 1 or 2 of the associated frame H when the louver board is in a closed position. 19 designates shields which are` secured to the facing` elements 17, said shields each comprising a skirt portion 20, which is extended into the pocket of the associated element 111, and an integral flange portion 21 which is secured to the associated facing element 17. 22 designates angular elements which are secured to the shirt portions and constitute parts of the rectangular frames 6 of the louver boards 5.

ln the use of my improved window sash, and when the louver boards 5 thereof are in closed positions,'the facing elements 17, in cludingr the inwardly extended fianges 18 thereof, enclose the channel members 16, and the close contact'between the inner ends of the iianges 18 and the side members 1 and 2 of the frames H, together with the presence of the channel members 16, provide baffles which prevent passage of rainwater and snow into the pocket 15. Also, when the louver boards are in open positions the channel members prevent rainwater and snow from passing freely into the pocket 15. When the louver boards 5 are moved to open positions the skirt portions 2O of the shields 19 are of such width that said slrirt portions are always eX- tended into the pockets 15, hence the openings at the opposite ends of the louver boards are always closed by said skirt portions, whereby rainwater, wind, and snow are prevented from passing beneath the open louver boards at the opposite end thereof. Also, there will be sufficient friction between parts of the louver boards and adjacent parts of the sashes to maintain said louver boards in'open positions.

When it is desired to lock the louver boards 5 in closed positions, the locking devices 9 are moved to the position in which the two upper locking; devices shown in Fig. 3 are illustrated, in which position the curved portions 10 of said locking devices embrace the lower ends of the louver boards located above said locking devices in a manner to prevent outward movement of said lower ends of said louver boards. When it is desired to unlock the louver boards so that the lower ends of same,

may be moved outwardly, the operating portions 12 of the locking devices are moved upwardly, as shown at the lower portion of Fig. thus moving the curved portions 10 of the locking devices downwardly and releasing the louver boards located above the locking devices so operated.

It will be not-ed on inspection of Figi. 2 that when the louver boards 5 and the parts associated therewith are in closed positions the upper sash of the window may be moved vertically without hindrance from said louver boards, inasmuch as these parts are located inwardly of the parting strips A of the window frame A which, with the elements Ab, provide guideways for said upper sash.

In Fi fg. l I illustrate a window sash of the sliding type constructed in accordance with this invention. In this form of the invention the side members 1 are recessed as at 25, to receive an angle element 16. The frame of the louver board 5 includes a facing element 17 having a iiange 18 and an angle member 21, and a shield 20 is secured to the facing element 17 and extends into a pocketl l5 provided by the elementlt. The slidable sash Fa is arranged for vertical movement in guideivays provided by the members 26 and 27 of the Window frame, and the -louver boards in this form of the invention are adjustable just as are the louver boards of the form of the invention illustrated in Figs. l, 2, and 3.

It is obvious that the locking devices prevent passage of cold air between the louver boards and into the room when said louver boards are in closed positions.

I claim:

l. In combination With a Window sash, a louver board, means for pivotally connecting said louver board to said Window sash to permit adjustment of said louver board with respect to said Window sash, shields at the opposite sides of said louver board for preventing entrance of inclement elements beneath the louver board at the opposite sides thereof when same is in an open position, and elements fixed to the Window sash at opposite sides thereof providing pockets into which said shields are extended.

2. In combination with a Window sash, a louver boa-rd, means for pivot-ally connecting said louver board to said Window sash to permit adjustment of said louver board With respect to said window sash, shields at the opposite sides of said louver board for preventing entrance of inclement elements beneat-h the louver board at the opposite sides thereof When same is in an open position, and U- shaped elements fixed to the Window sash at opposite sides thereof providing pockets into which said shields are extended.

3. In combination With a Window sash, a plurality of independently movable louver boa-rds, means for pivotally connecting said louver boards to said Window sash to permit adjustment of said louver boards with respect to said WindovxT sash, and means for locking said louver boards in their closed positions, said means comprising pivotally supported elements arranged partially in side and partially outside of the Window sash.

4. In combination with a Window sash, a plurality of independently movable louver boards, means for pivotally connecting said louver boards to said Window sash to permit adjustment of said louver boards with respect to said Window sash, and means for locking said louver boards in their closed positions, said means comprising pivotally supported elements arranged partially inside and partially outside of the Window sash, and said pivotally supported elements being provided with portions shaped to engage the louver boards.

5. In combination With a Window sash, a plurality of independently movable louver boards, means comprising rods supported by the Window sash for pivotally supporting said louver boards to permit adjustment thereof With respect to said Window sash, and means for locking said louver boards in their closed positions, said means comprising pivotally supported elements arranged partially inside and partially outside of the Window sash, and having portions shaped to engage the louver boards, said locking means being pivotally supported by the rods which pivotally support said louver boards.

In testimony that I claim the foregoing I hereunto affix my signature.

EDWARD S. KELLY.
